Another common desalination process is Reverse Osmosis. It involves a solvent passing through a semi-permeable membrane; meaning this particular membrane only allows some molecules to penetrate or pass through. The solvent will then go into a solution with higher concentration of molecules.
Most genetically engineered fish are used in basic research in genetics and development. Two species of fish, zebrafish and medaka, are most commonly modified because they have optically clear chorions (shells), rapidly develop, and the 1-cell embryo is easy to see and microinject with transgenic DNA.ome GM fish that have been created have promoters driving an over-production of all fish growth hormone. This resulted in dramatic growth enhancement in several species, including salmonids, carps and tilapias.
The GloFish is a patented and trademarked brand of genetically modified (GM) fluorescent fish. A variety of different GloFish are currently on the market. Zebrafish were the first GloFish available in pet stores, and are now sold in bright red, green, orange-yellow, blue, and purple fluorescent colors.t around the same time, a separate deal was made between Taikong, the largest aquarium fish producer in Taiwan, and the Taiwanese researchers to market the green medaka in Taiwan under the name TK-1. In the spring of 2003, Taiwan became the first to authorize sales of a genetically modified organism as a pet.
